LOOK FOR LOOSE-LEAF BINDERS.

To all whom "it may concern:

Be it known that I, LEONARD R. DIOKER- son, a citizen of the UnitedStates, and a resident of the city of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inLooks for Loose-Leaf Binders; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

In the numerous loose leaf binders heretofore constructed an objectionhas been found to their use because of the difficulty in protecting theledger or binder from un authorized insertion or removal of sheets orleaves whereby the value of the record afforded by the contents might beseriously affected. In numerous instances also, the purchaser does notcare for, and therefore does not require a lock in connection with suchdevices and it therefore necessitates in many instances, theconstruction of two distinct types or forms of binders, in one of whicha lock is installed, and in the other of which (though otherwise perhapsa facsimile) no lock is used. This necessitates carrying double thestock on hand, and is, of course, objectionable to the dealer.

The object of this invention is to afford a construction in which thelock may or may not be employed as the purchaser may elect, and whichenables the purchaser, even though the device wnen first purchasedshould be provided with a lock, to dispense with the same at will, andto use the same with or without the lock indeterminately at any timeduring the use of the device.

It is also an important object of the inven tion to afford in connectionwith a device such as described, a removable lock normally secured inplace in the binder but which can only be removed from the binder by theuse of a key, which thus permits the actuating mechanism for the binderto be operated.

It is also an object of the invention to afford in a device of the classdescribed a shaft operated binder provided with an aperture to permitaccess to the shaft for operating the same, said aperture adapted to besecurely closed by the engagement of a removable lock therein.

Specification of Letters Patent.

Application filed February 1, 1909.

Patented July 19, 1910.

Serial No. 475,328.

The invention consists in the matters hereinafter described and morefully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a fragmeir tary inner face View of abinderembodying my invention showing the lock in place. Fig. 2 is a section online 2-2 of Fig. 1. Fig. 3 is an end elevation of the binder backshowing the binder locked by the plug ging of the aperture by means ofthe lock. Fig. at is a top plan view of the lock, showing the sameremoved from the binder and in locked position. Fig. 5 is a similar viewbut she-wing the lock adjusted for removal from the binder. Fig. 6 is asection of the lock taken on line 66 of F ig. 3.

As shown in the drawings: the binder back is of the three piece typecomprising a central back plate A, clamping plates B-B, integrallyconnected with inwardly turned lateral back flanges Z), and as shown,provided with telescoping impaling posts bb which are rigidly connectedon the respective clamping plates.

tigidly connected with the back plate A, at the end thereof, andaffording guides for the back flanges 2), between the same and said backplate, is a transverse metallic bar C, which is supported at somedistance above the inner face of the central back plate, owing to theconvexity of said back plate, as shown in Figs. 2 and 3. Said backplate, as shown, is provided at each end with an end plate a, rigidlysecured thereon in any suitable manner, and as shown, provided with anaperture in one end to receive the key or other tool for engaging theangular end (Z, of the right and left threaded actuating shaft D, as isusual for expanding and contracting the binder. As shown, said aperturein the end plate a, is slotted on one side to permit the insertiontherethrough of the lock E, which comprises a cyllndric barrel 6,provided in one end with an aperture to receive the key 0', thereinwhereby said barrel may be rotated, and rigidly secured on one side ofthe barrel is a casing or seat 0 in which is pro vided spring impelledpins 6 in a familiar manner adapted to register with, and engage againstcorresponding shorter pins 6*, in the barrel and bearing on the outerends of which are balls 6 adapted to be engaged by the wards of the key,as shown in Fig. 6,

when the key is fully inserted to adjust the shorter pins 6 in thebarrel, and the pins 6 in the ward seat to a position to permit therotation of the barrel. Secured on the outer end of the barrel is a dogF, which is adjusted on the barrel to extend at a right angle with theward seat or case when the parts are adjusted, as shown in Fig. 6, andhence the only position at which the key can be inserted or removed.

As shown in Figs. 1, 2 and 3, a stop pin 0, is secured to the under sideof the bar C, which is sufiiciently long to lie closely to the ward seator case 6 and prevents rotation of the lock in the aperture.

The operation is as follows: Should the user desire to lock the binder,it is only necessary to insert the look into the aperture in the endplate a, after the binder is properly adjusted, and turn the key tobring the wards again into register, or to the position shown in Figs.1, 2, 3, 4, and 6, in which position the insertion of any tool tooperate the actuating shaft, is, of course, impossible. Of course, anysuitable lock may be employed for this purpose by the use of which theaperture for the actuating tool may be closed. I therefore do notpurpose limiting this application for patent otherwise than necessitatedby the prior art.

I claim as my invention:

1. The combination with a binder provided with a key aperture and atransverse bar above the key aperture, of a lock adapted for insertionin the key aperture comprising a barrel, a casing, a rotatable memberjournaled on the end of the barrel and a pin secured to the transversebar to engage the casing and prevent turning thereof.

2. The combination with a binder provided with a key opening and a barsecured above the key opening of a lock adapted for insertion into theopening comprising a casing, a member adapted to be rotated at a rightangle therewith and lock in said position and means secured to the barfor preventing turning of the casing.

In testimony whereof I have hereunto subscribed my name in the presenceof two subscribing witnesses.
